[R] Selecting / creating unique colours for behavioural / transitional data

[Ross Culloch]

Many thanks yet again for your reply, thanks for that method, i gave it a go
and i checked 'mycols' and sure enough it had selected the chosen colours
and listed their names, but when i used it for making the graph warnigs
informed me that the supplied colour in not numeric or character.
